No arguments here. If I lose the battle to keep them in the lavatories, the best alternative might be at the entrance to the manufacturing cell, away from ESD items, but still close enough for use.

"In order to mitigate field-induced CDM [Charged Device Model] damage, the ESD program shall include a plan for the handling of process-required insulators. If the field exceeds 2,000 volts/inch, steps shall be taken to either: A) Separate the insulator from the ESD-sensitive device by a distance of 30 cm (12 inches); or B) Use ionization or other charge mitigating techniques to neutralize the charge." [ANSI/ESD S20.20-2007 section 8.3] To keep 12 inches from ESDS at all times, it would be better for the dispensers to be in the lavatories or mounted on a wall in the ESD protected area, rather then be placed on the ESD workstation. Gene Felder [log in to unmask] -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Douglas Pauls Sent: Tuesday, November 10, 2009 6:10 AM To: [log in to unmask] Subject: [TN] Sanitizer and Lotion Paper Good morning all, My esteemed colleague, Dave Hillman, reminded me that I had not turned Technet back on after some recent travels to the UK and people had some questions regarding the status of the paper I am (still) working on with regards to the effects of sanitizers and lotions. I checked over the archives to see what I missed. I apologize if people thought it would be in the IPC Midwest proceedings. It is still in progress. The intent was to publish for Apex 2010. I asked the IPC if they were still accepting abstracts for Apex 2010 and was told they were, even though it was past their previously published deadline. So I submitted the abstract, with rosy dreams of Best Of Conference Paper, lauds and accolades and all the other silly crap that goes through my head when I have had too much Diet Dew. My paper was rejected by the Apex committee........... because it was turned in after the deadline. Duh. So, they want to know if I would do it as a Poster Session. Hell no, the work is too good for a poster session. I am currently on "backup status" in case someone backs out of the conference. Did not leave a good taste in my mouth. Anyway, I am still working on the paper, though it is nearing completion. All the testing is done. First lesson learned: never tell anyone else in the corporation that you are doing such a study. You get bombarded with requests to test "my favorite brand", "I like the smell of this one, can you test it?". I have concluded that the hand sanitizers are not an issue. They do not significantly transfer to the substrate and I saw no significant degradation due to the sanitizers. I looked at 3 that were essentially 62% alcohol and 1 that was non-alcohol based. The current raging debate here is whether to allow the sanitizers out on the manufacturing floor, which I don't want, preferring to keep them in the lavatories. With 16 confirmed H1N1 deaths in Iowa to date (2 yesterday), we have people who would be putting this on every 10 minutes if we let them. The second raging debate is whether those great big plastic dispensor jugs constitute an ESD hazard. I wish I had not opened this can of worms. The jury is still out on the lotions. I do see some degradation of dielectric strength, SIR, and lap shear strength for adhesion (saw some improvement though in some cases), but not a great deal. Keep in mind that we do still have a final cleaning step prior to conformal coating. After that cleaning, everyone is required to wear gloves, negating the effects of hand contact. Now I am waiting for someone to ask the question of whether they can put hand sanitizer on the glove surfaces. Hillman, don't you dare............ I expect to have the paper finished sometime in early December. I have some upcoming travel (i.e. plane/airport/hotel room time) so may be able to finish earlier. I will post the executive summary of the paper to the forum in advance.
